Definitions

  • PLASTIC PIPE V Filed June a. 1966 Sheet 3 of s Ma's/v70)? Wilhelm Hes lo!- Hitov'ne/s United States Patent O 3,440,822 PLASTIC PIPE Wilhelm Hegler, Goethestrasse 2, Bad Kissingen, Germany Filed June 8, 1966, Ser. No. 556,105 Claims priority, application Germany, June 23, 1965,
  • Plastic pipe to be used for drainage purposes must have a significant resistance to collapse by reason of the weight of earth on top of it or by reason of other ground pressures which build up around it.
  • this invention includes, as one of its aspects, the provision of plastic pipe having reinforcing ribs and a smooth wall interior.
  • the plastic pipe has substantially straight inside walls in the longitudinal direction, has longitudinal grooves in the inside walls, and has apertures between the ribs communicating with these grooves.
  • FIG. 1 is a front elevation partially in section of a pipe according to this invention
  • FIG. 2 is a transverse section through a pipe made according to this invention.
  • FIG. 3 is a partial transverse section of one type of pipe according to this invention.
  • FIG. 4 is a longitudinal section through a portion of a pipe made according to this invention.
  • FIG. 5 is similar to FIG. 4 showing a modification thereof
  • FIG. 6 is similar to FIGS. 4 and 5 showing a modified pipe according to this invention.
  • FIG. 7 is similar to FIG. 3 showing a modified access aperture arrangement
  • FIG. 8 is similar to FIG. 3 showing a modified access aperture arrangement.
  • the drainpipe of FIGS. 1 to 4 is a drainpipe in which the external, transverse ribs 1 form a double-threaded screw.
  • On the inside of the pipe a plurality of longitudinal grooves 2 are provided, and at the points at which these longitudinal grooves 2 cross the valleys 3 between the transverse ribs, the water admission openings 4 are punched into the wall which is very thin at these points.
  • water admission openings are provided between all of the ribs.
  • a filter 5 can be inserted between these ribs above the aperture, as represented in the right half of FIG. 1.
  • FIG. 3 shows that, at the point where a water inlet opening 4 is located, the wall thickness is substantially slighter than at the other points between the reinforcing ribs.
  • water inlet openings are located between every pair of ribs
  • water inlet openings are provided only between alternate reinforcing ribs, and a filter cord 5 can be provided between such ribs covering said aperture.
  • the cross ribs can be constructed as double ribs, as shown in FIG. 6. In this case the water inlet openings are located between the ribs which are spaced more widely apart while providing no aperture between the ribs which are narrowly spaced apart.
  • the longitudinal grooves 2 may also be so deep that they reach into the valley bottom 9 between reinforcing ribs, so that, at those points at which the longitudinal grooves intersect with the valley bottom, openings are produced, and it is not necessary afterwards to cut or punch openings into the pipe.
  • This pipe form can be manufactured, however, only when no pressure difference between the interior of the pipe and the exterior is required in the manufacturing process, or when the longitudinal grooves are not provided until after the external formation of the pipe has been concluded.
  • This invention has an unexpected advantage attached thereto.
  • Plastic drainpipes as previously manufactured, have had certain difliculties attached thereto. If the water admission apertures are large, silt gets into the pipe and builds up in the pipe thus causing a restriction in flow and eventually stoppage of water flow. On the other hand, if the water admission apertures are small, silting is reduced or even prevented; but deposits form on the walls of the aperture which increasingly restrict the already small opening and eventually block it closed completely. This latter phenomenon is particularly prevalent in iron bearing soils in which case such blockage is referred to an ochering up. The tendency for small inlet aperture to be blocked, as set forth, has been found to be markedly reduced or prevented where the wall thickness of the pipe is reduced.
  • the water inlet openings can be made in any desired shape, e.g. circular, ovate, rectilinear, free form, etc. It is preferred to provide a relatively long, relatively narrow slit as the inlet aperture since this structure tends to permit the entry of large quantities of water while keeping out at least larger particles of silt.
  • the plastic pipe according to this invention may be manufactured of substantially any desired material such as vinyl resins, acrylonitrile-butadiene-styrene resins, polyacetal resins, synthetic or nautral rubber, polyethylene, polypropylene, etc.
  • a plastic pipe having relatively smooth and longitudinally straight interior Walls, reinforcing ribs transversely disposed about the outside wall thereof, longitudinal grooves in the inside wall thereof, and water inlet openings disposed in the thin portions of the wall of the pipe between the ribs and in registry with said grooves.
  • each of said openings is defined by a peripheral terminal edge of line thichness formed by a slanting surface in said thin wall portions.
  • a pipe as claimed in claim 1 constructed of at least one member selected from the group consisting of vinyl resins, polyacetal resins, acrylonitrile-butadienestyrene resins, polyethylene resins and polypropylene resins.
